视频监控即服务(VSaaS)或基于云计算的视频监控无疑成为了2010年的热门话题，而且对VSaaS的兴趣转变促使VSaaS供应商数量的增长。但这种炒作能在2011年转华为市场增长吗?

　　围绕VSaaS的炒作不是没有根据的;对电信/互联网服务供应商、中央间开展和工程/集成商来说，每月的经常性收入商业模式是非常吸引人的。这种由一些解决方案供应商促进的业务增值无疑是一个有说服力的主张。能够实现远程监控视频数据的冗余，真正的“即插即用”安装，对视频的远程访问，以及视频监控系统较低的成本等都是鼓励这个市场成长的因素。

        展望2011年，VSaaS的应用当然更有可能取代其它的应用。最大的成功将会是客户拥有的多个站点中每个站点只要求4个或更少的摄像机。这些特殊应用包括移动电话信号塔、小型连锁零售店、石油钻塔和电力分站。这些应用都需要安防或监控，但是如果在多个站点只想花费安装数百个而不是数千个传统DVR系统的费用的话，可以通过采用VSaaS方案来减少成本。

        因应减少摄像机数量的需求，VSaaS有潜力成为打入以DVR和模拟摄像机占主导地位的视频监控市场的破坏性力量。为了加快这一进程，一些服务商已经开始提供与其他服务集成的VSaaS解决方案。这样做的好处是使得服务从简单的安防应用，转变为多平台的服务。VSaaS供应商越来越多地增加提供与他们的解决方案集成的服务的数量，这些服务包括：能源管理，销售终端(POS)，视频分析，家庭自动化以及门禁控制。供应商持有这种信念的原因在于，终端用户将更有可能通过采用一个拥有强大附加值的解决方案，而不是仅仅是一个视频监控或者安防应用，尤其如果成本是客户考虑的首要因素的时候。

        目前来说，特殊应用将是VSaaS市场增长的最大初始动力。为了在大众市场取得成功，VSaaS供应商可能越来越需要与其他服务来进行整合，比如家庭自动化、POS或能源管理方面。一旦VSaaS能够显示出绝对和强大的附加值，VSaaS市场就可能显著成长。

The Mist Clears on Cloud-Based Video Surveillance

Video Surveillance as a Service (VSaaS) or cloud based video surveillance was certainly a hot topic in 2010 and that interest in VSaaS turned into an increase in the number of VSaaS providers. But can this hype be translated into market growth in 2011?[nextpage]

The hype around VSaaS is not unfounded; the recurring monthly revenue business model is very attractive to telcos/ISPs, central monitoring stations and installer/integrators. The value-add promoted by some solution providers is certainly a convincing proposition. The ability to achieve remote redundancy of video data, true ‘plug n' play' installation, remote access to the video, and a lower cost video surveillance system are all factors that will encourage this market to grow.

Looking ahead to 2011, certain applications of VSaaS are more likely to take off than others. The most successful will be customers with multiple sites that each require (four or less) cameras. These niche applications include mobile phone masts, chains of small retail shops, oil rigs and electricity sub-stations. These applications all require security or monitoring, but the cost of installing hundreds if not thousands of traditional DVR systems across multiple sites can be reduced by having a VSaaS solution.　　

VSaaS has the potential to be the disruptive force needed to break into the low cameras count, DVR and analogue camera dominated video surveillance market. In a bid to speed up this process, some service suppliers have started to offer VSaaS solutions integrated with other services. The benefit of this is that it turns the service from a simple security application, to a multiplatform service. An increasing number of VSaaS providers offer the following services integrated with their solution: energy management, point of sale (POS), video analytics, home automation and access control. The belief is that end-users will be more likely to adopt a solution with a strong value-add, rather than just a video surveillance or security application, particularly if cost is the primary decision factor.

For the time being, niche applications will have the greatest initial traction in the growth of the VSaaS market. To succeed in the mass market, VSaaS providers are increasingly likely to require integration with other services such as home automation, POS or energy management. Once VSaaS can demonstrate a clean and strong value-add, the market has the potential to grow significantly.
